Interview some contractors and after choosing one, schedule a time to walk through the home with a contractor to get a better estimate.Have the home inspected.

The reason is not that there are no tenants looking, but rather: A new building is an unknown to tenants, so there are no reviews online and the amenities are a question mark; andDuring interim occupancy, which is when most investors put their units up for lease, the common areas are not yet finished, and construction activities are still taking place in the building; andThere is usually a flood of units hitting the market for rent in a new building, so anyone who choose some nicer upgrades or colours, or who has a better layout, will lease first. 6 - Transportation Anyone noticed that with each year that goes by, it takes a little longer to get around the City?

Even though their lists can work well for certain types of direct mail efforts (depending on what types of properties and owners you're targeting), they're not always the best fit for everything, and some counties (usually the more rural, sparsely populated ones) have issues like the ones you're seeing.If current tax delinquent data is part of what you're relying on, I'd say your better option would be to go directly to the county and get it (because the county is always going to have the most current and accurate information on hand).If you're looking for some other services that provide lists in a similar fashion (though, most of them don't even give the option of tax delinquent data), you can always check out this review I did on 5 of the more well-known services to choose from.
